The earthquake and resulting tsunami off the coast of Japan has proved yet again how the internet offers an information lifeline to the world in a time of crisis.

The internet was partly designed so US military communications could withstand nuclear attack, and is proving equally resilient in natural disasters and upheavals in global politics — via redwolf.newsvine.com

When Lloyd Borrett set up a website in the mid-1990s for a local computer company, he had to move overseas to find a suitable domain name – well before it was fashionable to do so.

The restrictions on Australian domain names meant that he could not reserve expert.com.au for Expert, an IT business later acquired by Indian outsourcer Infosys for $31 million. Similar generic names such as florist.com.au or computer.com.au were not for sale.

Basically, any word in the dictionary was excluded, said Mr Borrett, who now works for anti-virus and security company AVG . So I went to Norfolk Island instead and registered expert.nf because they had just opened up a registry there.

The Australian rules were gradually relaxed and the trade in domain names ending in .au has boomed.

Last night, total registrations on Australia’s country-code top-level domain reached 2 million, indicating that Australian businesses, which make up almost 86 per cent of .au domain names, prefer local internet real estate. Almost a quarter of a million .au domains have been sold this financial year — via redwolf.newsvine.com

The large distributed denial of service (DDoS) attacks that hit the WordPress.com blog publishing platform last week originated from China, according to the founder of the site.

A DDOS attack involves harnessing hundreds or thousands of computers to simultaneously bombard a web site with data so it becomes overwhelmed. The computers in such attacks have typically been infected with malware so they can be used without the consent and awareness of their owners.

The attacks, which brought slowdowns to the WordPress.com site, were severe enough to interfere with the company’s three data centers in Chicago, San Antonio and Dallas. The site has since returned to normal as of Monday — via redwolf.newsvine.com

In theory, stopping spam is easy: just make it uneconomic to send millions of messages by charging for each one sent, or make senders authenticate their identity to stop address spoofing and simplify blocking.

In practice, that would involve building a secure, parallel e-mail infrastructure linking electronic authentication with real-world identities: a daunting task. Yet that’s just what Germany is about to do.

De-mail — a play on the country-code abbreviation for Deutschland (Germany) and the word e-mail — is a government-backed service in which all messages will be encrypted and digitally signed so they cannot be intercepted or modified in transit. Businesses and individuals wanting to send or receive De-mail messages will have to prove their real-world identity and associate that with a new De-mail address from a government-approved service provider. The service will be enabled by a new law that the government expects will be in force by the end of this month. It will allow service providers to charge for sending messages if they wish — via redwolf.newsvine.com
